Synchronize with ntpd

Daniel Ubeda — Wed, 05 Mar 2003 20:08:13 GMT

Hi,

I have two HP9000's, with xntpd process running. One of them is the server and the other is the client.
How can I get the difference between two 9000's ??

the command is: ntpq server1 ???

thanks

I think the command you are looking for is:

# ntpq -p

# man ntpq
for more information.

Basic NTP info:

ntpq -p (* synchronize *)

/sbin/init.d/xntpd start/stop

/etc/rc.config.d/ntp.conf (* configuration file *)

However, SAM will do it all if you let it!

Since I don't have access to a real ntp site to sync my 2 9000 systems to, I run the following in cron once a day to keep track of the drift between the 2, until I can get access to an NTP site:

/usr/bin/remsh /usr/bin/date; /usr/bin/date

This will not give you an exact time match, but is close. I then do a date -a when they drift more than a minute apart.

Small script to identify the time on two machines. Best way to sync time would be one machine get to a stratum 1 server on the internet and then have the second one to sync to the first. You do not have to allow your UNIX boxes to be the direct internet access. Put a dumb windoz on the network, have it access the internet and sync itself. You may have to have it (the windoz box to a broadcast out) and then have your UNIX boxes sync to it.
